Re: Nipper and Cisco configuration results
by Subba Rao 04 Apr '09

04 Apr '09

I looked at the configurations yesterday on the routers. The vty line does not have any "transport" line below it. All the routers showing "Rlogin enabled" have similar configuration. What are the default services that are enabled for vty on IOS 12.4? I know there are only telnet, SSH and Rlogin. Is there any particular sequence that IOS processes the vty access?

Add it back & nipper says it's disabled... Do you have a "transport input telnet" on each vty? If not, does adding it fix the nipper report? Regards, Lee

BGP and ios upgrade question
by srg 03 Apr '09

03 Apr '09

Hello: A little customer has a Cisco 1841 router running ios 12.3(8r)T8. At the end of this mail is a "show version" from the router. Now, he wants to run BGP. His current ios version 12.3(8r)T8 does not support BGP. According to Cisco feature navigator, ios version 12.4(24)T (c1841-ipbasek9-mz.124-24.T.bin) can run in the 1841 and supports BGP (note that feature set is IPBASE): http://tools.cisco.com/ITDIT/CFN/Dispatch?act=feature&imageid=1321931&platf… 12.4(24)T requires 128MB DRAM and 32MB flash Remote peers will announce ONLY the default route to the 1841 My questions are: 1) It is common that a version with an IPBASE feature set supports BGP (some docs says that bgp support is included in "SP" services feature set)? 2) Will ios version 12.4(24)T run OK in the 1841? I think the response will be YES because Cisco feature navigator says that it is supported and the router has the DRAM and FLASH needed by 14.4(24)T. 3) Must the customer pay in order to download 12.4(24)T or he can download if he has a valid Cisco maintenance contract for that router? ------------------------------- show version Cisco IOS Software, 1841 Software (C1841-IPBASE-M), Version 12.3(8)T8, RELEASE OFTWARE (fc1) Technical Support:http://www.cisco.com/techsupportCopyright (c) 1986-2005 by Cisco Systems, Inc.

Nipper and Cisco configuration results
by Subba Rao 03 Apr '09

03 Apr '09

I am using Nipper for verifying my Cisco configuration. Nipper is finding the "rlogin" service that is not in the configuration. I have searched the access lists and do not see it anywhere. The explanation by Nipper about this finding, "....Telnet protocol implemented by this service...." is confusing. Here is the Nipper's output: ______________________________ Rlogin Service Settings The Rlogin service enables remote administrative access to a CLI on Cisco Router Devices. The Telnet protocol implemented by th service is simple and provides no encryption of the network communications between client and the server. This section details the Rlogin settings. Description Setting Rlogin Service Enabled Service TCP Port 513 ______________________________ I have checked a few other routers where SSH was not enabled with the same results. Can someone explain why Nipper is saying "Rlogin is enabled" when I do not see it in the configuration file? Is there something else that I need to be looking at? Thank you in advance for any help.

Re: Nipper and Cisco configuration results
by Subba Rao 03 Apr '09

I will check this as soon as I go to work this morning. One thing I noticed was about the Nipper results is that any router where SSH was disabled/Rlogin was enabled and vice versa. I will go thru the configuration file once again. Thank you very much for checking this out!

Joe, Thank you for replying. I am asking about the Nipper complaint. Why is Nipper report saying "Rlogin" is enabled when I don't see any ACL in the config? Using IOS 12.4 Cheers, Subba Rao --- On Thu, 4/2/09, Jo¢ <jbfixurpc(a)gmail.com> wrote: From: Jo¢ <jbfixurpc(a)gmail.com> Subject: RE: Nipper and Cisco configuration results To: castellan2004-nsm(a)yahoo.com, nanog(a)nanog.org Date: Thursday, April 2, 2009, 9:09 PM Subba, Sorry, perhaps I am confussed about the nature of your question? Did you have acls up for logging these attempts and they weren't logged? or are you asking for help from the Nipper portion of this as to why its reporting this item. With my logging turned up to debug I do see entries about RSHPORTATTEMPTs, but I suspect theres a lesser logging for that based on facility. At 12.3 I don't see any sort of problem with an open Rlogin/Rsh, and I have tested this on a router running a very minimal configuration. Hands out DHCP and does OSPF, but that's about it. Can you clarify your problem a bit? -Joe ________________________________ From: Subba Rao [mailto:castellan2004-nsm@yahoo.com] Sent: Thursday, April 02, 2009 8:25 PM To: nanog(a)nanog.org; Jo¢ Subject: RE: Nipper and Cisco configuration results I did not scan the routers yet with nmap.

I don't see that behavior (rlogin/rsh) by default, but I'm a few revisions behind on the latest. @ 12.2 I do see from the router: RCMD-4-RSHPORTATTEMPT Attempted to connect to RSHELL from 192.168.1.52 from nmaps, but theres no response to the SYN packet of the attempting IP. I think this has been the case since w-a-y earlier versions of IOS for logging levels but not sure at which level. Looks to only be logging an attempt, no session is made, sort of like a firewall just letting you know there was an attempt. The router gets the request but it falls on deaf ears, no one home. Unless perhaps theres some other sort of flag/bit that can be presented to open that connection(extremely doubtful) I don't believe theres any way to connect. Perhaps turning down your logging will prevent your testing program from reporting a false positive? I'd snoop/sniff the traffic and see if your router is SYN/ACK-ing the request of rlogin/rsh to be sure. <sarcasm>And make sure their not to close to one another, incase their using undocumented internal wireless units as a means to complete the connection, those Cisco guys you know..</sarcasm> Regards Joe Blanchard > -----Original Message----- > From: Subba Rao [mailto:castellan2004-nsm@yahoo.com] > Sent: Thursday, April 02, 2009 6:33 PM > To: nanog(a)nanog.org > Subject: Nipper and Cisco configuration results > > I am using Nipper for verifying my Cisco configuration. > Nipper is finding the "rlogin" service that is not in the > configuration.
